IMPROVEMENT IN SEWING-MACHINE HEIVHVIERS.

Specilication forming part of Letters Patent N0. 52,646, dated February13, 1866; antedated February 5, 1866.

To all whom it may concern:

Be it known that I, GEORGE C. OvEnHrsER, of Ionia, in the county ofIonia and State of Michigan, have invented a new and useful Improvementon a Hemmer for Sewing-Machines, by the use of which hems of variouswidths can be accurately laid and readily made 5 and I hereby declarethat the following is a full, clear, and exact description of theconstruction and operation of the same, reference being had to theannexed drawings, making a part of this specification, in whichl Figure1 is a perspective view. Fig. 2 is a view of the apparatus inverted,with the sliding gage removed. 3 is a plan of the sliding gage as itappears when detached from the frame. Fig. 4L is a transverse sectionthrough the middle of the hemmer.

Like letters represent like parts in all the figures.

A is the base of the frame, through which a thumb-screw passes to securethe apparatus on the sewing-machine. B is the thumb-screw passingthrough the base. O is the opening or slot in the base through which Bpasses. D is the steady-pin in under side of base A. E is the uprightpart of the base of the frame, over the end or top of whichapressure-spring passes. F shows the position of the hinge on E. G isthe bar between the clamp end and hinged end of the frame. H is thepressurespring on the bar G. I is the smoothingspring under the bar G. Kis that part of the sliding gage which passes through the clamp endofthe frame. Lis a piece attached to the free end of the bar G forsupporting the hernmer and guiding the sliding gage M. It is made in twoparts, and is made to act as a clanip on M. P is athumb-screw foropening the clamp L. M are the arms of the sliding gage which enters theclamp, and K is a part of the same, projecting therefrom at rightangles; Nis the heminer.

I construct this improvement on a hemmer of brass and steel or any othersuitable material.

The-apparatus is secured on lthe plate or table of the sewing-machine bymeans of the thumb-screw B passing through the base of the frame A. Theopening or slot O, Fig. 2,

is made oblong for the purpose of permitting the frame to be moved whenthe thumb-screw B is loosened, so that the stitch may be placed upon theedge of the hemor near it.

In addition to the thumb-screw B, I employ a steady-pin, D, Fig. 2..inthe under side of the base A, for keeping the hennning device fromturning to one side.

On the top of the upright part of the base of the frame E is a hinge, F,by means of which the bar G is attached to the upright part and base ofthe frame and made movable. On this bar G a spring, H, (the end ot'which is attached to E,) bears, thus keeping the gage firmly on thematerial while it is passing under it to the folding-guide or heinnierN.

The smoothing-spring I is placed parallel with and under the bar G, withone end attached to the base of the frame A, while the other end pressesupon the arm K of the sliding gage at the point where it passes throughthe clamp-jaws. This spring I keeps the folds of the work smooth as itpasses to the hemmer N.

On the end of the bar G which is opposite to its hinged end there is aclamp, L, attached, with beveled jaws, which can be compressed by athumb-screw passing through the hole P, for the purpose of securing thesliding gage in required positions. When the sliding gage K M isadjusted to give the required width to the hem its lower side is flushwith the lower side of the jaws of the clamp L, so that the lower foldof the hem may pass under it freely, and the work is guided ina straightline by the arm W of the sliding gage, which is between or inside thefold of the hem.

On the clamp-jaw L, which is toward the needle of the sewing-machine,and as'near the smoothing-spring I as possible, the heminer N isattached, with its lower side Hush with the lower side of the slidinggage K M. As one fold of the cloth is made by the turn over the arm M ofthe sliding gage, it is only necessary to give it one turn more in thishemmerN to complete the hem. This permits the hemlner N to be simplyconstructed with a single turn inside, as shown in the transversesection through the y middle ofthe hein mer, Fig. 4. rlhe hemmer N ismade broader at the base, near the smoothA ing-spring I, Where the clothentersit, than at the point Where the olotli emerges (with the hemturned ready for stitching) for the purpose ot' turnin g the hem.

When I use my improvement I attach it to the plate or y table ot' asewing-machine by means ofthe thumb-screw B in the base ot' its frame;set the sliding gage K M to give the required Width of hem and secure itin that position by means of the thumb-screw in the jaws ot the clamp L;then pass the oloth or other material to be hemmed under the slidinggage K M, and, folding the side of the cloth over the guiding-arm M ofthe sliding gage and under the smoothing-spring I, enter the end of itin the hemmer N near the smooth-
